Application June 25, 1940, Serial No. 342,393

4 Claims.

My invention relates -to an attachment for an ordinary shade rollerbracket to prevent unwanted shifting of the shade roller from engagementwith the open slot in the bracket, and the primary object of theinvention is to provide a simple and efficient arrangement of thischaracter which is readily removable to enable removal of the shaderoller from the bracket.

Other important objects and advantages of my invention will be apparentfrom a reading of the following description taken in connection with theappended drawing, wherein for purposes of illustration, 2. preferredembodiment of my invention is shown.

In the drawing:

Figure 1 is a front elevational view of a conventional shade rollerbracket of the open slot type, showing the attachment of the inventionmounted thereon.

Figure 2 is a side elevational view of Figure 1, looking from right toleft.

Figure 3 is a horizontal sectional view taken through Figure 1approximately on the line 3-3 and looking downwardly in the direction ofthe arrow.

Figure 4 is a front perspective view of the attachment.

Referring in detail to the drawing, the numeral 5 generally designatesthe conventional slotted roller shade bracket which involves the plates6 and l which are commonly attached to the window frame within which theshade roller is mounted, the intermediate concavo-convex por tion 8between the portions 6 and 1 extending away from the window frame 9 inthe manner illustrated in Figure 2 so as to provide a space ll) betweenthis intermediate portion 8 and the frame 9. The portion 8 is providedwith the shade roller element receiving slot H which opens through oneside of the said portion as indicated by the numeral l2, therebyordinarily permitting the said element of the roller to escape from theslot ll when the roller is contacted by any object having a tendenc todislodge the same from its normal position.

The attachment which is generally designated I9 is devised to preventthe element of the roller shade from coming out of the slot H under thementioned circumstances, and this attachment comprises an elongatedtapered flat base plate portion I4 which has two longitudinalsubstantially parallel slots i5 and [5, respectively, cut inwardly fromthe small end thereof as illustrated in Figure 4, with the resultingmiddle finger I! made longer than the other resultant fingers, so as toprovide for the bends l8 and I9 which define the catch portion of theattachment, and the laterally directed finger 26 which provides thereleasing handle of the attachment. The larger end of the plate M isprovided with a lateral extension in the form of an arcuate relativelynarrow plate 2| which is curved and beveled to substantially conform tothat portion of the exterior of the central part of the shade rollerbracket, as illustrated in Figures 1 and 3, in a position across theopen end I2 of the slot ll, thereby functioning as a stop and a guardfor'engagement by the mentioned element on the shade roller.

To install the attachment, the small end of the plate 14 is passed underthe portion 8 of the bracket, that is, between this portion and thewindow frame or the like 9, and the attachment is pressed in ahorizontal direction until the catch formed by the bends l8 and I9 snapsaround the opposite side of the central portion 8 of the shade rollerbracket. This completes the installation.

To remove the atachment when it is desired to remove the shade roller,it is only necessary to exert some pressure on the handle portion 20 torelease the catch from detent engagement with the central portion of theshade roller bracket, when the attachment is free to be withdrawn in adirection opposite from that from which it was inserted. The attachmentmay be made of one piece if desired.

Although I have shown and described herein a preferred embodiment of myinvention, it is to be definitely understod that I do not desire tolimit the application of my invention thereto, except as may be requiredby the scope of the subjoined claims.

Having described the invention, what is claimed as new is:

l. A device of the character described comprising a bar, a lateral armat one end of said bar, and a spring detent adjacent the opposite end ofsaid bar, said detent comprising a longitudinal finger defined bylaterally spaced longitudinal slots formed from the said opposite end ofthe bar, said finger having an intermediate portion deflected toward thesame side of the bar as said lateral arm and providing an abutmentopposed to said lateral arm.

2. A shade roller bracket comprising a substantially circular bodyhaving bevelled side walls. said body being formed with a transverseslot opening through one edge thereof, a removable slot guard comprisinga bar engaged across the wider end of said body, a lateral arm formed onsaid bar adjacent one end of said bar, said lateral arm being curved tosubstantially conform to the curvature of the sidewall of said body andextend across the open end of said slot, and a spring detent adjacentthe opposite end of said bar, said spring detent being tensioned toengage the side wall of said body opposite said lateral arm for holdingthe guard in place.

3. A shade roller bracket comprising a substantially circular bodyhaving bevelled. side walls, said body being formed with a transverseslot opening through one edge thereof, a removable slot guard comprisinga bar engaged across the wider end of said body, a lateral arm formed onsaid bar adjacent one end of said bar, said lateral arm being curved tosubstantially conform to the curvature of the sidewall of said body andextend across the open end of said slot, and a spring detent adjacentthe opposite end of said bar, said spring detent being tensioned toengage the side wall of' said body opposite said lateral arm forholding'the guard in place, said lateral arm being acutely angulatedwith respect to said bar so as to conformably engage the bevelled sidewall of said body and thereby substantially completely close the openend of the slot.

4. A shade roller bracket comprising a substantially circular bodyhaving bevelled side walls, said body being formed with a transverseslot opening through one edge of said body, a removable slot guardcomprising a bar engaged across the wider end of said body, a lateralarm formed on said bar adjacent one end of said bar; said lateral armbeing curved to substantially conform to the curvatureof the sidewall ofsaid body and extend across the open end of said slot, and a springdetent adjacent the opposite end of said. bar, said spring detent beingtensioned to engage the side wall of said body oppositesaid lateral armfor holding the guard in place, said. spring detent comprising a springtongue defined by longitudinal slits formed in said bar, said tonguehaving a part deflected to the same side of said bar as said lateralarm, said part being deflected at an acute angle to conform to the bevelof the sidewall on said body whereby said plate is held engaged with thewider end of said body.
